Must the Mistakenest Mistake (レシピの卵！ダンカンは、これは冗談だと思っている！ Eggs for Recipes! Duncan thinks this is a joke!) is the third episode of Campers In The Wild.
The teams temporarily merge, and Lindsay and Beth and Duncan, Courtney and Julie compete in a cooking contest, and the recipe has to have an egg in it. Lindsay and Beth decide to make some ice cream from it. Duncan, on the other hand, ignores Christina's orders and makes a drink with no egg in it, causing him to be eliminated.
